Comparative sequence analysis of the phytochrome C gene and its upstream region in allohexaploid wheat reveals new data on the evolution of its three constituent genomes.

Abstract excerpt

Bread wheat is an allohexaploid with genome composition AABBDD. Phytochrome C is a gene involved in photomorphogenesis that has been used extensively for phylogenetic analyses. In wheat, the PhyC genes are single copy in each of the three homoeologous genomes and map to orthologous positions on the long arms of the group 5 chromosomes. Comparative sequence analysis of the three homoeologous copies of the wheat...
